This invention relates to a mount or means whereby a telescopic sightmay be supported on a rie or other firearm in a manner such that thetelescope sight will always be in accurate alignment with the bore ofthe firearm when in use.

In particular, the invention is designed to provide a simple and durablestructure which permits quick detaching of the telescope from the rifleand allows clip-loading bolt action rifles to be loaded from clipswithout detaching the telescope. The mount enables the telescope to be Yl; osition to clip-loading position and vice versa in a second or less.

V The use of iron sights on the rifle is permitted ,by shifting thetelescop to the cl 0 q ng posi- "tioni e cies, or n e e cing thetelescope when the use of iron receiver peep sights is desired. Themount does not interfere with the conventional base for receiver peepsights.

It should be understood that the term shooting position refers to theposition of the telescope directly over the bore of the rifle, and theterm clip-loading position denotes the position when the telescope isswung upward and to the left for inserting a clip of cartridges in thegun or for using iron sights on the gun.

Fundamentally, the mount is a structure having a shaft attachable to atelescope and which is journaled in a suitable sleeve mounted on thereceiver of the gun. The sleeve has a slot enabling detachment andattachment of the shaft, and also has enlargements in the slot, ornotches, engageable by arms extending from the shaft to the telescope,said notches permitting the swinging of the telescope from clip-loadingposition to shooting position and vice versa.

The more specific objects and advantages will become apparent from aconsideration of the following description taken in connection withaccompanying drawing illustrating an operative embodiment.

In said drawing- Figure 1 is a view in side elevation showing myimprovements applied to a rifle, the latter being fragmentary;

Figure 2 is a top or plan view offthe parts of Figure l;

Figure 3 is a vertical section taken on the line 3-3 of Figure 1;

Figure 4 is a cross-sectional view passing through the plane of theclick latch used for the telescope mounting shaft; and

Figure 5 is a longitudinal section taken on the line 5-5 of Figure 3.

Referring specifically to the drawing wherein like reference charactersdesignate like or similar parts, Il! represents a small firearm such asa Model '70 Winchester rifle. It is to be understood that myimprovements may be used on firearms, particularly the small type;generally. Of such rifle I0, the barrel is shown at II and the receiverat I2, the illustrations being fragmentary.

A conventional sighting telescope shown at I3 in the drawing is inshooting position, directly over and almost touching the receiver. Itis, however, movable in the path of the arrow at the top of Figure 3, s0as to be placed in clip-loading position, that is the positioning thatfacilitates the loading of the rie from clips or the use of iron sights.l

Said telescope I3 is carried by a rod or shaft which may be hollow asshown, or solid, as preferred, and from which a pair of clamp arms I5extend radially, the same being integral with or Welded to the shaft I4.The clamps are slit and somewhat resilient as shown, in order to havebands I6 encircling the telescope tightly clamped thereto by means ofscrews I'I passing loosely through openings I8 in terminal arms I9 ofthe clamps and being screw-threaded in openings 20 in the main portionof such clamps. I'hus the telescope may be adjustably and removablysecured to the rod or shaft I4.

Said shaft or rod I4 is snugly journaled 4in a sleeve or barrel 2I of asuitable mount generally designated 22. The mount is secured in place asby means of screws 23 directly to the receiver I2, as shown.

The sleeve or barrel 2| has a longitudinal slot 24 in the top thereofand extending from end to end, and the sleeve along one side of its Wallat the slot 24 is enlarged to provide notches at 25. By reason of thisconstruction, the shaft I4 may be applied to thel sleeve by sliding itlongitudinally into the latter with the clamp arms I5 passing throughthe slot 24 to a position where they may be turned on the axis of theshaft, into and out of the notches 25. y

By tightening the tapered thread screw caps 32, the sleeve 2I mayfrictionally bind the shaft I4 to any desired degree inV order to holdthe shaft and accordingly the clamp arms I5 and telescope in any desiredposition of adjustment or swinging of the arc suggested at the top ofFigure 3.

In both the ring or shooting position, as shown in the drawings, and theclip-loading position to which the parts maybe swung, as suggested .bythe curve in Figure 3, they are adapted to be 55 held -by a, suitablelatch 26, engageable in the respective positions mentioned with recessesat 21 and 28, provided in the rod or shaft I4. Latch 26 may be of anydesired shape, for instance that shown, or even a ball. A housing 29 isdetachably screw-threaded or otherwise attached to the sleeve 2l and itmounts the latch 26 and the coil spring 3D. The coil spring 30 isretained by a press flt plug 3|, or other suitable means. It will thusbe seen that the shaft or rod I4 and the telescope are adapted to belatched in both the shooting and clip-loading positions. The latch willbe displaced automatically as the telescope is moved from one positionto the other and will also produce a click in so doing.

I preferably provide means to close the ends of the slots 24 and suchmeans may take, for example, the form of caps 32 screw-threaded orotherwise detachably connected at 32 to tapered screw portions at theterminals of the sleeve 2|. These caps can normally be manipulated byhand after the shaft I4 is in place and removed singly or together, aspreferred, in detaching or replacing the shaft.

If desired, coin slots 34 may be provided diametrically on the caps 32to facilitate application and removal by means of a, coin or screwdriver. Such caps 32 are also preferably externally knurled as shown.

Various changes may be resorted to provided they fall within the spiritand scope of the invention. In particular, the sleeves may be madethicker at each end, so as to strengthen the ends and make the use ofend caps 32 unnecessary.
